Specification of Letters Patent.

Patented May 22, 319i? Application filed June 7, 1916. Serial Ill'o. 102,278.

To all whom it may concern: Be it known that I, ARTH R L. RUNYAN, a citizen of the United States of America,

and alresident of Waterloo, Blackhawkcounty, Iowa, have invented certain new and useful Improvements in Resilient Heels for Boots or Shoes, of which the following absorb shocks incident to walking on hard pavements or sidewalks.

Another object resides in the provision of a heel of the nature stated embodying among other characteristics a resilient member provided With cavities arranged whereby the walls between the cavities will be gradually caused to flow into the cavities under compression to reduce the volume of each of the cavities and thereby compress the air in the cavities under compression according to difierent weights placed on the heel by the wearer or according to shocks incident to walking on hard pavements or-sidewalks.

This object I have accomplished by 'themeans which is hereinafter described and claimed, and which is illustrated in the accompanying drawings, in which Figure 1 is a plan view of the upper face of my improved resilient heel, and Fig. 2 isa plan of its under face, with a closure plate fixed thereon and partially broken away. i

Fig. 3 is a vertical longitudinal section of said heel and closure plate as mounted under the heel pa'rtof a shoe sole, the said parts being sectioned on the line a-b of said Fig. 1. g p

.Fig. dis a fragmental perspective new of the heel, somewhat enlarged, to show the form and arrangement of two of the adjacent oppositely opening cavities therein Similar numerals ofreference denote corresponding parts throughout the several views,

The resilient heel-part '1 is'composed of rubber or any other suitable yieldable resilient substance. It is provided on both its upper and under faces with like cavities 2 and 3 respectively of the form of a truncated pyramid. The cavities 3 are alternated transversely in alinement with the ities of one set overlapping the other set of cavities throughout the greater portion of the length of thesame. The walls between the cavities are approximately of equal th ckness, so as to yield equally on the appllcation of a weight suificient to deform the structure.

The heel-part 1 may be cemented, or secured in any desired or usual way to a sole 5 of a shoe,or upon a truncated leather heel.. Preferably, a closure plate 4, of leather, rubber or an other suitable material may be cemente or otherwise'united as by nails 7 and washers 8 in sockets 6 to filled with air, in case sufficient weight is imposed upon the heel, its cellular structure yields resiliently, compressing the air in said cavities elastically, and so the heel' cushions the shocks of use most efiectively. The cavities may be of different forms than that shown, although the form disclosed is preferably the preferred formation of the cavities. T contemplate, however, providing cavities of different form or dimensions, constituting the same, in any event, so that the walls between the cavities will be gradually thickened and caused to flow into the cavities under compression to reduce the volume \of each of the cavities from the inner ends thereof and thereby compress the air in the cavities according to the difierent weights placed on the cushion member by the wearer of my 'imprqved shoesole. Having described my invention, what I claim as new, and desire to secure by Letters Patent, is: A I 1. In a heel for shoes, a tread member, a resilient cushion interposed between said tread member and the rear end of the sole of the shoe, said cushion member having inner and outer series of relatively small outwardly tapering, air containing cavities therein, one series of cavities opening out ing short of the outer face of the cushion "member, the other series of cavities opening out through the outer face of the cushion member and terminating short of the inner face of the cushion member, all of the cavi ties being so arranged that one series of cavities overlap the cavities of the other 1w series throughout the greater portion of the length of the latter, and being so constructed that the side Walls of each series of cavities under compression are gradually thickened and caused to flow into the cavities .to reduce the volume of each of the cavities under compression from the inner ends of the cavities and thereby compress the air in the cavities under compression according to the weights placed on the cushion member, the outer face of said tread member having sockets therein and fastenings passed through the sockets oi the tread member and the edges of the cushion member and into the sole of the shoe..

2. In a heel for shoes, a tread member, a resilient cushion interposed between said tread member and the rear end of the sole of the shoe, said cushion member having inner and outer series of relatively small outwardly tapering, air containing cavities therein, one series of cavities opening out through the inner face of the cushion member and having their opposite ends terminating short of the outer face of the cushion member, the other series of cavities opening one series overlap the cavities of the other 3 series throughout the greater portion of the length of the latter and so eonstructedthat the side walls of each series of cavities under compression are gradually thickened and caused to flow into the cavities to reduce the 3 volume of each of the cavities under compression from the inner ends of the cavities and thereby compress the air in the cavities under compression according to the weights placed on the cushion member, said tread 4 member having the shape of the flat layers of an ordinary heel, and means for securing said tread member and said cushion member to the sole of the shoe.

Signed at Waterloo, Iowa, this 5th day of 4 June, 1916.
